Hi, 

my iBook G4 seems to be rather slow at compile time. The processor is a 1GHz
model but the kernel detects it as a 534MHz. Why ?

Does the kernel just read hardcoded information somewhere or is there an
issue to fix cpu detection ?

I am running NetBSD 2.0.2_STABLE.

Output of dmesg:
...
total memory = 768 MB
avail memory = 734 MB
mainbus0 (root)
cpu0 at mainbus0: Version 0x8003 (Revision 0x0101), ID 0 (primary)
cpu0: HID0 8410c0bc<EMCP,EICE,DPM,ICE,DCE,SGE,BTIC,FBIOB,ABE,BHT>
cpu0: 534.98 MHz, 256KB L2 cache

Best regards,
Mathias.
